Sharp PN-ME432 RS-232 / IP control commands

Summary

External control spec for the Sharp/NEC PN-ME series LCD monitor (PN-ME432/502/552/652). Supports RS-232C and LAN (TCP) control via a framed binary protocol (CTL commands and VCP get/set opcodes) with XOR block-check codes. Covers power, input selection, schedule, picture/audio settings, tile matrix, security lock, and diagnostics.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated in source
addressing:
  port: 7142
auth:
  type: none  # inferred: no transport auth procedure in source (C21D is a device feature lock, not transport login)

Traits

traits:
  - powerable    # inferred: CTL-C203-D6 power control present
  - queryable    # inferred: many status read / VCP get commands present
  - levelable    # inferred: volume, backlight, contrast set commands present
  - routable     # inferred: input source select commands present

Actions

# ── Framing ────────────────────────────────────────────────────────────
# Full frame = Header(7 bytes) + Message(STX..ETX) + BCC(1) + CR(0Dh).
# Header = SOH(01h) | Reserved(30h) | Destination | Source | MsgType | Length(2 ascii).
# BCC = XOR of all bytes from Reserved..ETX (excludes SOH). Delimiter = CR (0Dh).
# `command:` below holds ONLY the Message body (STX..ETX) verbatim; the caller
# must wrap it with header + BCC + CR per section 4. All payload bytes are
# ASCII-encoded hex (1 data byte -> 2 ASCII hex chars). e.g. byte 3Ah -> '3','A'.
# CTL MsgType header byte: 'A'(41h) request / 'B'(42h) reply.
# VCP MsgType header byte: 'C'(43h) Get / 'D'(44h) Get-reply / 'E'(45h) Set / 'F'(46h) Set-reply.

Notes

Source references "NEC LCD monitor" in its overview text; the PN-ME family is marketed by Sharp Electronics (Sharp acquired NEC's display business). Manufacturer set per operator input.
Byte encoding: every data byte is transmitted as 2 ASCII hex characters (e.g. byte 3Ah -> ASCII '3'(33h) 'A'(41h)). Lengths and opcodes in the header/message follow this rule.
Full frame wrap: every command: in Actions is the Message body only (STX..ETX). The controller must prepend the 7-byte header (SOH 01h, Reserved 30h, Destination, Source, Message Type, 2-ascii Length), append the BCC (XOR of bytes from Reserved through ETX, excluding SOH), and terminate with CR (0Dh).
BCC example (source 4.3.1): XOR of bytes 30h 41h 30h 45h 30h 41h 02h 30h 30h 31h 30h 30h 30h 36h 34h 03h = 77h.
Command intervals (RS-232C and LAN): keep command byte interval within 100 ms (RS-232C); send next command only after receiving the monitor's response. After Power ON/OFF wait ~15 s; after input switch or all-reset wait ~10 s.
LAN timeout: monitor disconnects after 15 minutes of no communication; reconnect after such an interval.
Error replies: out-of-range settings -> monitor does nothing and replies Result Code 00h (no error); unsupported/non-executable CTL -> NULL message (CTL-BE); VCP command errors -> Result Code 01h.
Destination addressing: monitor ID 1-100 maps to addresses 41h-A4h; group IDs and '*'(2Ah)=all. See source section 4.1.1 conversion table.
CTL-CA20 (MAC read) appears in section 8.1 power-off allowed list but not detailed in section 5; command code inferred as 'C''2''2''0' family.


Spec ready. All 28 CTL commands and all ~105 VCP opcodes enumerated. Framing (header+BCC+CR) noted; `command:` fields hold verbatim message bodies. Power-off allowed-command list captured in Safety. Unresolved markers present for firmware, flow control, CTL-CA20 detail, electrical specs.

Notes

Source references "NEC LCD monitor" in its overview text; the PN-ME family is marketed by Sharp Electronics (Sharp acquired NEC's display business). Manufacturer set per operator input.

Byte encoding: every data byte is transmitted as 2 ASCII hex characters (e.g. byte 3Ah -> ASCII '3'(33h) 'A'(41h)). Lengths and opcodes in the header/message follow this rule.

Full frame wrap: every command: in Actions is the Message body only (STX..ETX). The controller must prepend the 7-byte header (SOH 01h, Reserved 30h, Destination, Source, Message Type, 2-ascii Length), append the BCC (XOR of bytes from Reserved through ETX, excluding SOH), and terminate with CR (0Dh).

BCC example (source 4.3.1): XOR of bytes 30h 41h 30h 45h 30h 41h 02h 30h 30h 31h 30h 30h 30h 36h 34h 03h = 77h.

Command intervals (RS-232C and LAN): keep command byte interval within 100 ms (RS-232C); send next command only after receiving the monitor's response. After Power ON/OFF wait ~15 s; after input switch or all-reset wait ~10 s.

LAN timeout: monitor disconnects after 15 minutes of no communication; reconnect after such an interval.

Error replies: out-of-range settings -> monitor does nothing and replies Result Code 00h (no error); unsupported/non-executable CTL -> NULL message (CTL-BE); VCP command errors -> Result Code 01h.

Destination addressing: monitor ID 1-100 maps to addresses 41h-A4h; group IDs and '*'(2Ah)=all. See source section 4.1.1 conversion table.

CTL-CA20 (MAC read) appears in section 8.1 power-off allowed list but not detailed in section 5; command code inferred as 'C''2''2''0' family.

Spec ready. All 28 CTL commands and all ~105 VCP opcodes enumerated. Framing (header+BCC+CR) noted; `command:` fields hold verbatim message bodies. Power-off allowed-command list captured in Safety. Unresolved markers present for firmware, flow control, CTL-CA20 detail, electrical specs. ## Provenance ```yaml source_domains: - business.sharpusa.com source_urls: - https://business.sharpusa.com/portals/0/downloads/manuals/external_control_mexx2_en.pdf retrieved_at: 2026-08-05T06:40:15.170Z last_checked_at: 2026-08-05T08:42:02.189Z ``` ## Verification Summary ```yaml verdict: verified checked_at: 2026-08-05T08:42:02.189Z matched_actions: 130 action_count: 130 confidence: medium summary: "All 27 outbound CTL and 103 VCP opcodes from source sections 5.1/6.1 are represented in spec; transport params match section 3.
